T 0 all whom it may cone-e; a.

Be it known that 1, CHARLES N. BARTON, a citizen of the United States, residing at Indianapolis, in the county of Marion and Stateof Indiana, have invented a new and useful Sectional Journal Box and, Hub Liner, of which the following is a specification, reference being had to the accompanying drawings, and to theletters and Hgures of reference marked thereon.

This invention relates to liners which are designed to be removably secured to wheel hubs and journal boxes for the purpose of reducing lost motion oi. the journal boxes longitudinally on axles or shafts, or of axlesor shafts relatively to the journal boxes, the invention having reference more particu larly to liners for wheel hubs and journal boxes of locomotives.

An object of the invention is to provide a liner of the above-mentioned characterv which shall be so constructed as to permit it to be applied or removed from place Without necessitating the removal of a wheel or a journal box from an axle or shaft on which they may be used. v

Another object is to provide'locomotive wheel hubs and journal boxes with liners of improved construction permitting ready re newal when wornaway in use to such an extent as to permit an undesirable amount of play or space between a wheel hub and journal box, and without remoylng the wheel axles from their customary places 1n a locomotive.

A further object is to provide an improved sectional hub or journal box liner and means for securing the liner in place so that the liner shall be firmly and reliably held in place and not be liable to be broken or dam,- aged in use, and which may be applled either to new machinery in the factory or to machinery in which lost motion has developed in service: which liner and securing appliances shall be reliable, durable and economical in use. 1

WVith the above-mentioned and other objects in view, the invention consists in a novel sectional liner having a novel holder whereby to removably secure the liner to a wheel hub or a journal box; and, the invention consists also further in the novel 1921. Serial No. 482,514.

faces wear away and require liners which till the undesirable space between the box and the hub resulting from the wearing When the locomotive is being built it may be supplied with the improved liners which may readily be replaced when worn away by new liners.

vThe inner end of the hub 2 is supplied with a holder designed to permanently re main thereon, but is not necessarily integral therewith. Preferably the holder comprises a disk-shaped plate 5 having a central aperture 6 corresponding in diameter to that'of the axle, which may be inserted in the aperture before the axle is inserted into the wheel hub, and in such case the'plate may be fitted tightly on the axle, as a collar. The holder plate obviously may be composed of several parts if desired to permit it to be placed on the axle atany time after the axle is securedto the wheel. The plate is placed against the innerend of the hub and essentially it is larger than the hub diametrically so as to produce a fiangedike circumferential guide rib on the hub. lhe plate is pro-- vided with a suitable number of countersunk holes 7 receiving securing bolts 8 which extend -through the hub 2. In some cases a similar holder plate 5" is likewise arranged on the side of the journal box 4.- opposite to the wheel hub and secured to the box by means of bolts 9 extending through the box. Eachsecuring bolt has a countersink head 10 arranged in the hole 7 and a nut 11 on the end ofthe bolt. 2 Each holder plate, which when made sepa. rately from the hub and the journal box constitutes the core of the improved liner, has two shoulders 12 and 18 oppositely arranged and formed preferably by recessing a portion of the periphery of the holder plate which forms the rib for holding the wearing part or shoe portion of the liner; and inthe preferred form of construction two other shoulders 14: and 15 are likewise provided on diametrically opposite portions of the plate or rib. Preferably also the peripheral portion of the plate gr rib' has recesses 16 and 17 therein to receive lugs.

Each liner or the wearing portion thereof that is designed to be renewed, comprises two similar segmental shoe sections having semi-circular face plates 18 and 19 respectively, and they have lateral rim portions 20 and-21 respectively that normally embrace the periphery of the holder plate or core, the rim p ortions having lips 22 and 23 respectively that engage the back of the holder plate while the wearing plates are close against the front face of the holder plate. One end of one of the two sections preferably has a slit 24: which separates a small portion of the rim 21 from the segment plate 19 so as to constitute a flexible tongue 25 Which originally extends outwardly beyond the arc of the rim; and likewise one end of the opposite segment is provided with a tongue 25. The opposite ends of the rim i i 1 p/ .1

of the segments have lugs 26 and 20 on the inner side thereof that are placed in engagement with the shoulders .12 and 1 respectively. 'lhe inner sides of the tongues have lugs 27 and 27' res ectivel that are forced r P Y into engagement with the shoulders and 15 respectively when the tongues are forced inward to theholder plate or guide rib.

In a modified form of construction the two sections of the liner have relatively thin hinge portions 28 and 29 at one end thereof that are connected together by means of pivot 30. The sections have also the locking lugs 26 and 27 describedabove. Prefer ably one section has a lug 81 onthe inner side of the rim portion that is received in the recess 16, and the companion section has a similar lug 82 that is received. in the recess 17, to assist in preventing the sections from turning on the holder or core.

lVhen assembling the parts of the liner, the sections are arranged on the holder or core and the lug 26 brought into engagement with the shoulder 1.2., and the lug 26 in en.- ga gement with the shoulder 14, afterwhich the tongues 25 and 25 are pressed or otherwise forced inward until the lugs 27 and 27' engage the shoulders 13 and 15 respectively, which then securelyhold the sections on the holder or liner core. "In case the sections are hinged together the tongue on one of the sections is forced into place so as to securelv lock the sections together-on the holder.

In practical use the face plates 18 and 19' wear away and when the lost motion or play occasioned by the wear becomes excessive the tongue 25 may be forcibly broken or cut oil": or may be forced outward to release the lug 27 from the shoulder 13, thus permitting the sections of the liner to be removed so that new liners or shoes may be applied'as before to the holders or cores of the liners.

Having thus described the invention, what is claimed as new is v I l. A sectional journal box and hub liner including a plurality of'segmental sections together comprising a continuous circular plate, .each section being provided with a lateral peripheral rim portion having locking'lugs at the inner side thereof, the rim portion of one of the sections having a flex,- ible portion .on which one of the lugs is fixed.
